DETAILED DESCRIPTION

OF THE EMBODIMENTS

A closed energy combined cycle system according to the present invention includes a power supply mechanism, a driving device, and at least one power generation device. The power supply mechanism is used for providing a high voltage, and operation of the driving device is controlled by the high voltage provided by the power supply mechanism. The driving device rotates the at least one power generation device to generate power through a transmission shaft, and the power generated by the at least one power generation device is supplied to the power supply mechanism and a load, in which the driving device rotates the transmission shaft at a high rotational speed and the transmission shaft rotates the at least one power generation device to generate the power.

The driving device rotates the at least one power generation device to generate the power at the high rotational speed through the transmission shaft, and the at least one power generation device at the high rotational speed has a higher power generation efficiency. Therefore, when the power generation device generates a few electric energies, the driving device can reduce the electric energies used for rotating the power generation device through the transmission shaft, thereby improving the power generation efficiency of the closed energy combined cycle system.

A structure and an operation method of the closed energy combined cycle system according to the present invention are further described hereinafter through an embodiment.

FIG. 1 is a system architecture diagram of a closed energy combined cycle system according to the present invention. In FIG. 1, the closed energy combined cycle system 10 includes a power storing device 12, a converter 14, a controller 16, a motor 18, a transmission 20, a transmission shaft 22, a rotational speed sensor 26, a generator 28, and a load 30. The power storing device 12, the converter 14, the controller 16, and the rotational speed sensor 26 form the power supply mechanism of the embodiment; the motor 18 forms the driving device of the embodiment; and the generator 28 forms the power generation device of the embodiment. In another embodiment, the closed energy combined cycle system may not include the transmission.

The power storing device 12 is used for providing power of a low voltage. The power storing device 12 may be a lead acid battery, a nickel-metal hydride battery, or a lithium battery, and so on.

The converter 14 is used for converting the low voltage of the power storing device 12 into a high voltage, and sending the converted power to the controller 16. The converter 14 may be a DC-to-DC converter or a DC-to-AC converter.

The controller 16 receives the power sent by the converter 14 and outputs a control power to the motor 18, so as to control operation of the motor 18, for example, controlling a rotational speed of the motor 18. The controller 16 may be an AC server, a DC server, or a frequency converter, and the motor 18 may be an AC motor, a DC motor, a magnetic levitation motor, or a permanent magnetic motor.

FIG. 2 is a schematic view of connection relations of a transmission, a motor, and a transmission shaft according to the present invention. In FIG. 1 and FIG. 2, the transmission 20 is disposed between the motor 18 and the transmission shaft 22. The transmission 20 changes the high rotational speed of the motor 18 into a different rotational speed, so as to rotate the transmission shaft 22. The transmission 20 is capable of raising or lowering the high rotational speed of the motor 18 (in the embodiment, the transmission 20 makes the rotational speed of the transmission shaft 22 higher than the high rotational speed of the motor 18.). The transmission 20 may be a segment transmission or a CVT. In another embodiment, it is unnecessary to dispose the transmission 20 between the motor 18 and the transmission shaft 22, and the motor 18 directly rotates the transmission shaft 22 (as shown by a dashed line in FIG. 1).

In FIG. 1 and FIG. 2, when the transmission 20 rotates the transmission shaft 22 (in another embodiment, the motor 18 directly rotates the transmission shaft 22, as shown by the dashed line in FIG. 1) to rotate the generator 28, the generator 28 operates at a rotational speed higher than the high rotational speed of the motor 18 (in another embodiment, the generator 28 operates at a rotational speed the same as the high rotational speed of the motor 18.). The transmission shaft 22 rotates the generator 28, so as to enable the generator 28 to generate power. The power generated by the generator 28 is supplied to the load 30, and is used for charging the power storing device 12. The generator 28 may be a DC generator or an AC generator.

The rotational speed sensor 26 senses the rotational speed of the transmission shaft 22, generates a rotational speed signal, and sends the rotational speed signal sensed by the rotational speed sensor 26 to the controller 16. The controller 16 controls the rotational speed of the motor 18 according to the received rotational speed signal, namely indirectly controlling the rotational speed of the transmission shaft 22.

Referring to FIG. 1 and FIG. 2, the operation method of the closed energy combined cycle system 10 according to the embodiment is described hereinafter.

Firstly, the converter 14 converts the low voltage of the power storing device 12 into the high voltage and sends the power of the high voltage to the controller 16.

The controller 16 receives the power of the high voltage and generates the control power according to the rotational speed signal of the rotational speed sensor 26, and outputs the control power to the motor 18, so as to control the operation of the motor 18 (for example, controlling the rotational speed of the motor 18).
